You need to re-install the Ti 84 Plus OS on both calculators, ASAP!!! You can fix these problems by installing the newest Ti 84 Plus 2.55v. MP OS, operating system. Use fresh batteries.

If you have a friend that has a Ti 84 Plus or, Ti 84 Plus Silver Edition you can connect the two calculators together through the USB or, IO link ports.

What can be done if a TI-83 Plus family or TI-84 Plus family calculator displays Garbage Collecting... for more than 20 minutes?

The garbage collection allows the cleanup of unused archive memory. It deletes unarchived variables from the user data archive and it rearranges the remaining variables into consecutive blocks. When a variable is unarchived, the Archive free memory amount increases immediately, but the space is not actually available until after the next garbage collection.

If garbage collecting is more than 20 minutes, the calculator has possibly locked up and will need to be reset.

The reset procedure will delete all the items that are in the memory of the graphing calculator. Use the reset procedure below:
• Remove 1 AAA battery. • Press and hold down the [DEL] key. • While holding down the [DEL] key, replace the AAA battery, and press the [ON] Key.

The message Waiting... Please install calculator software should appear. At this point, it will be necessary to reinstall the calculator's operating system.
• Connect the calculator to the computer using the TI Connectivity Cable or DirectUSB Cable.
